Use of Tunable Copolymers in Aqueous Biphasic Systems for Extractive Bioconvers...
Mendonça, Carlos M. N.; Veríssimo, Nathalia V.; Pereira, Wellison A.; Cunha, Paula M.; Vitolo, Michele; Converti, Attilio; Kurnia, Kiki AdiAqueous biphasic systems (ABSs) based on sodium polyacrylate (NaPA), ethylene oxide/propylene oxide (EO/PO) polymers, and (EO)x-(PO)y-(EO)x triblock copolymers were prepared and applied aiming at continuous fructooligosaccharide (FOS) production and separation. EO/PO hydrophilicity/hydrophobicity balance had a significant effect on ABS formation. To develop an integrated process including the continuous enzymat...
Characterization of levan produced by a Paenibacillus sp. isolated from Brazili...
Mendonça, Carlos M. N.; Oliveira, Rodrigo C.; Freire, Rominne K. B.; Piazentin, Anna C. M.; Pereira, Wellison A.; Gudiña, Eduardo JoséA levan-type fructooligosaccharide was produced by a Paenibacillus strain isolated from Brazilian crude oil, the purity of which was 98.5% after precipitation with ethanol and dialysis. Characterization by FTIR, NMR spectroscopy, GC-FID and ESI-MS revealed that it is a mixture of linear (26) fructosyl polymers with average degree of polymerization (DP) of 18 and branching ratio of 20. Morphological structure an...

M.; Pereira, Wellison A.; Gudiña, Eduardo J.A levan-type fructooligosaccharide was produced by a Paenibacillus strain isolated from Brazilian crude oil, the purity of which was 98.5% after precipitation with ethanol and dialysis. Characterization by FTIR, NMR spectroscopy, GC-FID and ESI-MS revealed that it is a mixture of linear β(2 → 6) fructosyl polymers with average degree of polymerization (DP) of 18 and branching ratio of 20.
